zzko Frequently
Asked Questions

zzko accepts three types of government-issued identity documents for KYC: your Bangladesh National ID Card (NID), a valid passport, or a driving licence. Upload clear, unobstructed photos of both the front and back of your chosen document through the Account Settings — Verification section. Most KYC reviews are completed within two hours during business hours. If your document image is blurry or partially obscured, you will be asked to resubmit, which may extend the review window.

Use the "Forgot Password" link on the zzko login page to trigger an immediate password reset. Enter the mobile number or email address linked to your account and zzko will send a secure reset link or OTP within 60 seconds. Follow the prompts to create a new password — it must be at least eight characters and include a mix of letters and numbers. If you no longer have access to the phone number or email on your account, contact zzko support via live chat to initiate a manual identity-verified reset.

No — zzko strictly enforces a one-account-per-person policy. Each player may hold only one active account, identified by their unique National ID, mobile number, and device fingerprint. Creating duplicate accounts to claim multiple welcome bonuses is a violation of zzko's Terms & Conditions. If duplicate accounts are detected, all associated accounts may be suspended, bonus winnings forfeited, and deposits returned. If you believe you have accidentally created a duplicate, contact support immediately to merge or close the extra account.

You can request account closure at any time through Account Settings — Responsible Gaming — Self-Exclusion, or by contacting zzko support via live chat. Before closure, any pending withdrawal balance will be processed to your verified payment method. Temporary deactivation periods of 30, 90, or 180 days are available if you want a break rather than a permanent closure. Permanent account closure is irreversible — your data is retained for regulatory compliance purposes but you will not be able to reopen the same account.

The minimum deposit on zzko is ৳300 via bKash, Nagad, and Rocket, and ৳500 via bank transfer through Dutch-Bangla Bank, BRAC Bank, or Islami Bank. The minimum withdrawal amount is ৳500 for all mobile money methods. There is no maximum single deposit cap for verified accounts, though individual payment providers may impose their own transaction limits. zzko does not charge any deposit or withdrawal processing fees on its end — any fees from your payment provider are outside zzko's control.

zzko supports a comprehensive range of payment methods tailored to the Bangladesh market. Mobile financial services include bKash, Nagad, Rocket (Dutch-Bangla Mobile Banking), and Upay. Bank transfer options cover Dutch-Bangla Bank, BRAC Bank, Islami Bank Bangladesh Limited (IBBL), Sonali Bank, and City Bank. International card payments via Visa and Mastercard are also accepted for verified accounts. zzko regularly adds new payment partners — check the Cashier section of your account for the latest available options.

Withdrawal requests on zzko are typically processed within one to three hours for verified accounts using bKash or Nagad. Bank transfer withdrawals to Dutch-Bangla Bank, BRAC Bank, or other local banks may take one to two business days depending on the receiving bank's clearing schedule. Withdrawals requested on Bangladeshi public holidays may experience a short additional delay. Your account must be fully KYC-verified before any withdrawal request can be approved — unverified accounts cannot process outgoing payments.

Withdrawal rejections on zzko typically occur for one of four reasons: your KYC verification is incomplete or pending review; you have an active bonus with wagering requirements that have not yet been met; the withdrawal account details do not match your verified identity documents; or a responsible gaming limit is in place that restricts outgoing transactions. The rejection notification in your account will state the specific reason. Contact zzko support via live chat if the reason is unclear — our agents can review the status of your request in real time.

RTP (Return to Player) is a percentage figure that describes the theoretical average proportion of staked money a slot game returns to players over a very large number of spins. For example, a slot with 96% RTP will, on average, return ৳96 for every ৳100 wagered across its lifetime. On zzko, each slot game's RTP is displayed in its game information panel. Higher RTP games from providers like NetEnt, Microgaming, and Pragmatic Play tend to offer better long-term value, though individual session results will always vary due to the inherent variance of each game.

Yes — zzko is fully optimised for mobile play directly through your phone's web browser, with no app download required. The platform is compatible with Android and iOS devices, and the interface adapts automatically to your screen size. All game categories — including cricket betting, slots, live casino tables, and fishing games — are accessible on mobile. For the best experience, zzko recommends using the latest version of Chrome or Safari on a stable internet connection, including 4G networks available across Dhaka, Chittagong, Sylhet, and other major cities in Bangladesh.

zzko hosts over 500 games from a curated selection of world-class providers. Slots and table games come from Pragmatic Play, NetEnt, Microgaming, and Spribe. Live casino experiences — including live blackjack, baccarat, and roulette — are powered by Evolution Gaming and Ezugi, both widely recognised as the industry's leading live dealer studios. The fishing game category, including King of Fishing, features titles from specialist arcade-style providers. zzko continuously expands its provider portfolio — the full current library is visible in the Casino Lobby once you are logged in.

All games on zzko use certified Random Number Generator (RNG) technology, independently tested and verified by the game providers themselves to ensure outcomes are statistically random and free from manipulation. Live casino games streamed by Evolution Gaming and Ezugi use physical cards, wheels, and real-time video to eliminate any possibility of software-side interference. zzko does not modify game logic or RTP values at the platform level — all games run exactly as certified by their respective providers. If you suspect a game malfunction, report it immediately through live chat for investigation.

Wagering requirements specify the total amount you must wager before bonus funds can be converted into withdrawable cash. For example, if you receive a ৳2,000 bonus with a 20x wagering requirement, you must place a total of ৳40,000 in qualifying bets before the bonus balance becomes withdrawable. On zzko, your progress toward the wagering target is displayed in real time in the Bonuses section of your account. Different games contribute different percentages toward the wagering target — slots typically contribute 100%, while certain table games may contribute at a lower rate. Always read the specific bonus terms before claiming.

Yes — zzko runs a regular calendar of promotions beyond the welcome bonus, including free spin packages on featured Pragmatic Play and NetEnt slot titles, weekly cashback offers that return a percentage of net losses, and seasonal campaigns during major Bangladesh events such as Eid, Pohela Boishakh (Bengali New Year), BPL season, and the ICC T20 World Cup. Promotions are visible in the Promotions tab once you are logged in. Free spin winnings are typically subject to a standard wagering requirement — the specific terms are stated clearly on each promotion card.

zzko rewards consistent players through a multi-tier loyalty programme. Points are earned automatically on every qualifying real-money wager placed across all game categories — cricket betting, slots, live casino, and fishing games all contribute. Accumulated points unlock higher loyalty tiers, each bringing benefits such as improved withdrawal limits, faster processing times, dedicated account management, exclusive reload bonuses, and invitations to special high-stakes tournaments. Your current tier and point balance are always visible in the My Account section. The full tier structure and point-earning rates per game category are detailed on the Loyalty Programme page within your account.

zzko provides a full suite of responsible gaming tools accessible directly from your Account Settings. These include daily, weekly, and monthly deposit limits that cap how much you can fund your account within a chosen period; session time reminders that alert you after a set duration of continuous play; a reality check feature that displays your net win/loss position at regular intervals; cooling-off periods of 24 hours to 30 days that temporarily restrict access; and a permanent self-exclusion option for players who need a longer-term break. All limit changes that reduce your access take effect immediately, while increases require a 24-hour cooling-off period before activation.

If you feel that gambling is negatively affecting your finances, relationships, or mental well-being, take action immediately — zzko's support team is available 24/7 to help. You can activate a self-exclusion or cooling-off period yourself through Account Settings at any time, without needing to contact support. If you prefer to speak to someone, reach out via in-platform live chat and ask for the Responsible Gaming team — they will assist without judgment and help you set up the appropriate limits or account restrictions. zzko strongly encourages all players in Bangladesh to gamble only with money they can afford to lose and to treat gaming as entertainment, not as a source of income. Players must be 21 years or older.
